研究异细胞质(异源细胞质)对小麦籽粒蛋白质含量的遗传效应问题,至今没有引起更多人的注意。虽然一些研究者曾报道:将普通小麦(Triticum aestivum)的细胞核导入某些亲缘种的细胞质,由于细胞质效应或核质互作,可以提高小麦籽粒的蛋白质和赖氨酸含量。但是他们大多是根据一个世代材料、一次实验的结果;有的供试材料置换回交次数不足。还有人指出:在大多数情况下,异细胞质系较高的蛋白质含量是由于细胞质影响产量性状变异的
Studying the genetic effect of different cytoplasm (heterologous cytoplasm) on the protein content of wheat grain has not attracted more attention so far. Although some researchers have reported that introducing the nucleus of Triticum aestivum into the cytoplasm of some relatives can increase the protein and lysine content of wheat grains due to the cytoplasmic or nuclear interactions. However, most of them are based on one generation of materials, the result of an experiment; some of the test materials replacement backfill less. Others point out that in most cases the higher cytoplasmic protein content is due to cytoplasmic variation in yield traits
